I am looking for an auto tune system for my 99 flhtci with magnetti marelli system. I have been looking at the mm conversion kit(closed loop) from thundermax but wonder if that my best option for an auto tuning system. My bike is a 99 and still stock with no problems with mm efi but I am putting on bassani power curves and 4" duals right now and need a fuel management system for pipe install right! So I was looking at an auto tune to go with my 95" head quarters build next year. Does anyone have advice for me because I need to change pipes soon and I think I have to add fuel management system before running pipes so I don't destory pipes finish? Help me please!! Thank You!!!
